 Nemobius utahensis Seudder. 



A single female of this species, previously known only from Spring 

 Lake and Salt Lake Valley, Utah, and Sedalia and Montevista, Colo- 

 rado, was taken at Albuquerque, September 14, where the species was 

 common in heavy weeds in the bottom-land. The capture of the 

 species at Montevista, Colorado, is interesting when taken with the 

 Albuquerque record, as the former locality is in the upper portion of 

 the Rio Grande valley.
